End-to-end test state fixtures (#7663) * Add network store for testing An alternative persistent state store has been created for use with e2e tests. Instead of reading state from disk, it tries to load state from a local fixture server running on port `12345` and serving state from the path `/state.json`, and returns a blank state otherwise. * Add e2e test fixture server A fixture server has been added for serving background state, which the background will read upon startup as part of restoring persisted state. The `signature-request` e2e test has been updated to use a fixture to bypass the registration step. The fixture used (`imported-account`) was generated by pausing midway through that test run

# End-to-end tests
This directory contains the fixture data used to bootstrap the individual e2e tests. Each sub-directory contains
one thing:
1. A `state.json` file that represents a the saved state for the extension (see _Generating fixture data_ below)
## Generating fixture data
Allow exporting state during e2e tests (#7860) As of #7663, an in-memory store was used in place of local storage during e2e tests, to facilitate the use of state fixtures. However, this made it difficult to export state during a test run. The instructions for exporting state to create fixtures assumed that local storage was being used. A new global function has been added to the background context to allow exporting state. This method is available during testing and development, and it works with either local storage or the in-memory store. The fixture instructions have been updated to reference this new function.

1. Load the unpacked extension in development or test mode
2. Inspecting the background context of the extension
3. Call `metamaskGetState`, then call [`copy`][1] on the results

You can then paste the contents directly in your fixture file.
