Follow up to detect more cases of entry modified in external changes resolver dialog

[ThiloteE]

BibEntryTypesManager will be addressed in a follow up pr. Should probably be a static class or an injected value.

It is still a problem that "resolve changes" pops up frequently for no good reason. I make a small edit to an open record, and the thing pops up.

Further, the screen options are confusing. After losing data often, I have discovered by trial-and-error that hitting "deny" preserves my edits. I've no idea why.
