Internal pbxProject.prototype.addTarget function not properly tested

[brody2consult]

Through Stryker mutation testing (see PR #61) of watch2 support (PR #56), I discovered that the internal pbxProject.prototype.addTarget function is not properly tested. Here are some possible mutations that would not be detected by the existing test suite:

Note that this diff includes the untested mutation that I reported in #73.

Considering that this function seems to play an important role in of the watch2 support, I would like to see it properly tested in the near future. However, I do not think that this should block merge of PR #56.
