Using priority shortcut on Project seems to create some request, which cannot be managed by Server, since Projects do not have priorities.

Steps to reproduce:
1) Go to Projects list (e.g. use "G+P" shortcut).
2) Select any Project (e.g. highlight it).
3) Press "P".
Result: Synchronization spinner icon appears in top right corner of the screen and after a while (around 30 sec.) error notification about slow network appears.
Expected result: Nothing happens.
