Describe the QA issue

Seen while testing client 2.11.1 on Linux Mint

• connect client with e.g. demo.owncloud.org
• Install nemo *-nemo boreser integration package.
• Restart nemo.
• overlay icons appear and right click has the owncloud sub menu.
• pause sync
• overlay icons disappear, no owncloud menu.
• resum sync
• overlay icons re-appear. owncloud menu is back.

Expected behaviour:

• The right click context menu is always there, as e.g. sharing settings are independant of any syncing on the local client.
• The overlay icons could also remain, and show e.g. a yellow (II) pause icon, just as the tray icon does.

Workaround: resume sync for a short moment, while accessing the context menu.

• The user has no indication in the file browsers, why no menus and icons are not showing.
• Energy and bandwidth is wasted for an unneeded 'resume sync' when I just want to edit a share.
