* Add a delay after connecting
This addresses an intermittent test failure where the MetaMask
Notification window cannot be found. It appears to be caused by the
Send button being clicked too soon after connecting to a dapp, before
the background has had a chance to process the approval. The premature
send is ignored and the window never appears.
This delay (2 seconds) should be sufficient time for the connection to
be processed. A later 5-second delay was also reduced to 2 seconds.
* Select onboarding buttons by button text
The onboarding buttons were being selected using the classname, which
was common to all onboarding buttons. This resulting in buttons being
selected just before a page transition, leading to an error about
the element reference being stale when a click was attempted.
The CSS class selectors have been replaced by text selectors, which
are more specific and shouldn't be at risk of resolving early. They're
also easier to read.
* Remove retypeSeedPhrase function
This function was used to re-type the seed phrase in the event that a
failure occurred when confirming the seed phrase. I'm not sure what
failure this was meant to address exactly, but this contingency hasn't
been needed for some time. We can tell that it hasn't been used because
it wasn't updated for the incremental account security changes, so it
couldn't have worked since then (it would have clicked the wrong
button).
* Add missing test descriptions
* Fix async tests that expect a rejection
These tests expected the function under test to return a rejected
promise, and had assertions to be run in the `catch` clause. However,
the tests would still pass if the function didn't reject, with
the assertions never being run.
The tests have been updated to fail if the function doesn't throw.
* Handle ignored promise rejection
In the case where `forceUpdateMetamaskState` rejects, the function
`setSeedPhraseBackedUp` would never resolve. It has been updated to
pass along the rejection instead.
* Return after rejecting promise in action
A few actions would continue after encountering an error, resulting in
errors being compounded. Instead all actions will now return after
encountering an error (which it looks like was the intention in these
cases anyway).
