Version calculation performance on tfs build

[IAfanasov]

Hi guys!

tnx for the tool!

I use GitVersionTask nuget package and have problem with really slow version calculation on the build sever. In total it (version calc) takes up to 10 minutes. For some reason GitVersion firstly get all commits and then filter them by commit date. It adds up several minutes. Also it branching same thing 3 times. I didn't get why it needs even one brunching. Tried to find some configuration tweeks in documentation without any success. Is it possible to optimize performance of GitVersion?

I"m seeing similarly long times and the one section that seems to be taking up the most time shows up as this in the log:

Any ideas why this might be taking a long time?

I'm running on a Windows 8-based Build Agent right now.

Turns out that this PR seems to have resolved the issue for us. #1100
