Fix for: Invalid transaction envelope type: specified type "0x0" but including...requires type: "0x2" (#14823)
* we should not call normalize if we're failing the transaction
refactor out update history
we should fail if un update we get an error and the warning message is
    error submitting.

Transaction Controller

Transaction Controller is an aggregate of sub-controllers and trackers exposed to the MetaMask controller.

  • txStateManager responsible for the state of a transaction and storing the transaction
  • pendingTxTracker watching blocks for transactions to be include and emitting confirmed events
  • txGasUtil gas calculations and safety buffering
  • nonceTracker calculating nonces

txMeta's & txParams

A txMeta is the "meta" object it has all the random bits of info we need about a transaction on it. txParams are sacred every thing on txParams gets signed so it must be a valid key and be hex prefixed except for the network number. Extra stuff must go on the txMeta!

Here is a txMeta too look at:

txMeta = {
  "id": 2828415030114568, // unique id for this txMeta used for look ups
  "time": 1524094064821, // time of creation
  "status": "confirmed",
