* Fixed Vivek's bug

Fixes #5850

What was happening:

It seems that his MetaMask had crashed while some new transactions had
been loading defaults. He probably had a network connectivity issue to
Infura (which we are working with Infura to address).

As a result of this network cutout, his three unapproved transactions
were not marked failed, and were not marked as `loadingDefaults =
false`, as their gas prices had not yet been estimated.

Normally this behavior is supposed to clean itself up when the
transaction controller starts up, via the
`TransactionController._onBootCleanUp()` function, but in this case,
during unlock, that function was unable to do its job because when it
requested the transaction list, the current network was in the `loading`
state, making it proceed as if there were no pending transactions.

To fix this, I am doing two things:
- Setting transactions to loadingDefaults = false in more catch blocks.
- Calling `onBootCleanUp()` when the network store's status changes, so
that it will re-trigger when loading completes.

* Fixed reference

* Fixed infinite loop bug

Was refreshing the tx list on every tx state change instead of just
network changes, creating an infinite loop.

* Add notes to tx updates to clarify logs
