chore: enable sqlite for enginev3

• update log levels so that detailed logs are written to diagnose testing issues
• fix issue in engine.init where error is always returned
• more detailed log messages

NOTE: the sqlite test suite doesn't work in ci which is why its skipped. currently testing is done locally
NOTE2: @tma66 - do we never initialize the FileStore for enginev3?

[jonathanyeung]

DendronEngineV3 shouldn't be aware of anything related to SQLite - it should only know about the IDataStore interface, otherwise we're losing the benefits we gained by creating those interfaces. We need to pull all init logic out of this class/file.

What happens if a user has the SQLite setting flipped in their configs and is using the web extension? wouldn't it cause problem at this point?

update: disregard. web implements a separate engine at this point. though this should probably move elsewhere like Jonathan mentioned to account for the eventual engine convergence.

FileStore

FileStore is never used. But kept there for backwards compatibility until we clean it up

Same comment about the init process that @jonathanyeung

if I'm understanding it correctly, sqlite backend wouldn't work currently with the web extension unless we make it work in memory and in the browser. So I think it makes sense that this is tied to FileStorage for the time being.
