Improve functionality

Compatible with older version sessions file.

Add more action to edit localDraft

Save all drafts.

Update

Use Kazv::LocalDraft instead of three std::string.

I don't have Macos.

Serialization correctly.

buildbot is broken

Draft can now be restored after switching rooms or reopening kazv.

autoCache will not be modified

Connect the function that opens the file to the KazvIOJob instead of the FileHandler that can be destroyed at any time.

Use failWithResponse(r) instead of lambda

Currently Kazv cannot remember a room is in the state of editing or replying to an event, which makes restoring a draft difficult to achieve. I think this feture should be divided into several diffs instead of being completed in one diff.

Show failure message

Open file when cache success

When I enter a wrong password, then open the input box again, the old password will still be retained. Especially when I click the "show password", the input box will retain this setting. This is obviously inconsistent with the behavior of most similar software and may lead to unexpected occurrences.

Actually I cannot build the flatpak package using the instructions, but this is not relevant to this diff. Please refer to D287.

@nannanko I cannot seem to reproduce this bug. Is it still a problem for you? My guess is that it is somehow fixed by @apr3vau .
