Unified state filter

[CAGS295]

Summary of Changes

• Unify TransactionRequest scans for stacks and bitcoin rpc calls.
  1. State is scanned when processing transaction requests. The filtering logic was repeated in a few places (e.g. stacks vs bitcoin homolog functions). This logic was a little inconsistent after the introduction of 'strict' mode, where 'log and exit early' supersedes panics in non-strict mode.
• Retry signing_&_broacasting upon error; Transient errors like nonce collision must not stop task processing. Transient signing errors (notoriously nonce collision errors) do not halt task processing unless running in' strict' mode. Previously, errors we dealt with a dummy task event that caused issues because it was generic enough to be picked by other task-processing calls, causing the function to complain about multiple task instances being updated. Moreover, the transient errors caused the incomplete task to be stuck in limbo.

It should fix #328 and #333. It may also fix #268, but I haven't tested it explicitly.

I ran a deposit/withdrawal loop until errors popped. You can find the source code here.
