Title: Fix for TeamCity infinite loop

It solves the problem described here:
http://devnet.jetbrains.net/message/5460892#5460892. When you trigger
builds using webhook and have enabled VCS labeling, TeamCity goes into
infinite loop: it is notified on every push, every push triggers the
build, every build makes a tag and pushes it.
