Slight cleanup following #16944

This should allow future scriptpubkeymans to transparently work, since the current plan is to have ismine always be spendable.

cc @achow101 @Sjors

conversation ensued on IRC after reading #16373 (comment) since this pattern should be followed in each place we use this behavior for LegacyScriptPubKeyMan

Note to other reviewers: ISMINE_ALL = ISMINE_WATCH_ONLY | ISMINE_SPENDABLE. When WALLET_FLAG_DISABLE_PRIVATE_KEYS is set, no coins can be ISMINE_SPENDABLE. Therefore ISMINE_ALL leads to the same behavior as ISMINE_WATCH_ONLY

This isn't quite what I was thinking.

The thought was that you would do either checking for LegacyScrriptPubKeyMan or ISMINE_ALL, not both. Since ISMINE_WATCHONLY is not intended to be used outside of LegacyScriptPubKeyMan, you could just check for whether it's LegacySPKM and set ISMINE_WATCHONLY if it is. Otherwise you just use ISMINE_SPENDABLE.

Alternatively, because ISMINE_ALL is ISMINE_WATCHONLY | ISMINE_SPENDABLE, for all watch only wallets (disabled private keys), you can have the filter be ISMINE_ALL. That will be sufficient to cover LegacySPKM and future ScriptPubKeyMans which will exclusively use ISMINE SPENDABLE. Of course all of the watch only stuff will need to check for disabled private keys, but we already do that.

I don't think doing both of those things are necessary.

If I have to choose, I'll stick with the Legacy check + ISMINE_WATCH_ONLY since it's easier for me to understand the purpose/scope of the code. Updated.

ACK 6beb900 modulo question and suggestions below. Code review/built/ran tests. Would test coverage be helpful here?

Reduced changes as per discussion to just affecting the ismine filter, rather than fAllowWatchOnly.

This smaller diff in e1e1442 seems good and the build/tests pass. Started looking at a test which, per @instagibbs suggestion, would define a new spk_man, add watchonly coins, then check they aren't returned by ListCoins.
