It doesn't seem this closes #439 yet - can you confirm? There are still tests left commented - the ones that edit state on IMAP.

[Kharchevskyi]

I reenabled only tests which doesn't change state on Imap server.

Good - please update the PR description so that it doesn't close #439 since there will be more tests to re-enable later, once we figure out how to run them without messing up the IMAP server data.
