do not count a transaction-in-progress as a transaction...

[mrose17]

Auditor: @bbondy

Test Plan:

• Start with vanilla state, enable ledger payments
• Fund wallet
• Quit browser, find reconcileStamp: 14... in ledger-state.json and change the 4 to a 3
• Start browser wait for payment to be made
• 'View Payment History... link will not appear until all votes cast.

Fixes #5371

Fixes #5441 (i can’t reproduce it — neither could @ayumi — but i cleaned up a little bit of logic to make it easier to follow.

Fixes #4274 ... use the test plan in that issue.

@ayumi pls review

[ayumi]

confirming resolves #4274 (Ledger should track windows created before wallet)

tab performance is similar to master @ 33cbd18 (original report #4274 (comment))

half confirming test plan resolves #5371 (Payment history link should not appear until votes cast).
waiting votes to be cast to confirm the payment history link.
