Not being able to logout when "Latest transactions" is still syncing

[t00k]

Issue description

I am not able to logout properly when the "Latest transactions" are still trying to sync. Using tangbebay.com-node and Latest transaction is just spinning and spinning and spinning. When trying to click on Log out Firefly just freezes and is unresponsive.

Wallet version

FF 0.2.1
Win 10

Is it a repeatable issue?

Y

Steps To reproduce the issue

1. Login with tanglebay-node.
2. Meanwhile "Latest transactions" is still syncing/fetching, try and log out.

Expected behaviour

Firefly should be logged out.

Actual behaviour

Firefly window freezes and you are not able to do anything unless force closing the app from task bar.

Errors

No errors in Error log or Developer Tools.

Other findings

Tried changing back to the default nodes. When changing nodes, and trying to go back into the wallet, the whole app freezes and you need to force-close.

Steps to reproduce this error

1. Go into Settings.
2. Change to Node setting to Automatic.
3. Click on the "Wallet" in the left row.
4. Firefly freezes.

^ No errors in error log or Developer Tools.

When trying to delete the Firefly-folder in APPDATA, Windows won't let me and gives me an error with "Cannot complete the request since the folder or a file in this is opened in another program".

Problem is, every app that could have used it, is closed.

Deleting the Files one by one in C:\Users\t00k\AppData\Roaming\Firefly shows me that the files still being used and thus not letting me delete the folder is;
C:\Users\t00k\AppData\Roaming\Firefly_storage_\asdf which includes wallet.db and wallet.stronghold
C:\Users\t00k\AppData\Roaming\Firefly\Dictionaries which includes sv-SE-3-0.bdic
