2.0.315 package includes libgit2_tests.exe

[AArnott]

Next to the runtimes\win-x86\native\git2-182d0d1.dll file is a libgit2_tests.exe file that is both large and likely unnecessary to using libgit2sharp.

This is in 2.0.315. It did not appear in 2.0.315-alpha.0.9.

Hmm, interesting. Not sure how that happened. Definitely not intentional.

2.0.316 and newer didn't have this problem, so I'm still not sure how those snuck in for 2.0.315. Going to close this and keep an eye on any new packages to make sure it doesn't happen again.
