Description of problem:
I use mbsync to keep a local maildir copy of my email account.
I usually handle it with mu4e or mutt but I tried to configure it also for evolution.

When I added my maildir folder to evolution accounts if loaded correctly all my emails, but when I closed it I noticed that my local maildir folder was completely broken.

The initial folder structure was the following:
1) all the first level folder where present into my ~/Mail folder
2) all the subfolder where present into the parent folder with a dot prepended.

Example:
INBOX
Archive
    -> work
Sent


~/Mail/INBOX
~/Mail/Archive
~/Mail/Archive/.work
~/Mail/Sent

After runing evolution the structure was the following:
1) all the first level folder where present into my ~/Mail folder with a dot prepended
2) all the subfolder where present into my ~/Mail folder with the parent folder prepended and also a "_2E" as a path separator.
3) all ma previous folder were left

~/Mail/INBOX
~/Mail/Archive
~/Mail/.Archive
~/Mail/Archive/.work
~/Mail/.Archive_2Ework
~/Mail/Sent
~/Mail/.Sent



Version-Release number of selected component (if applicable):
evolution-3.10.4-2.fc20.x86_64

How reproducible:
The issue if fully reproducible, just redowload your emails and add them back to evolution.



Steps to Reproduce:
1. configure a local mail sync with mbsync (or offlineimap)
2. load that folder with evolution
3. close evlution and inspect the content of the maildir
