Saving while watch:test is being run crashes chrome/phantom

[patkujawa-wf]

Version: 0.7.1 Repro:

1. gulp watch:test or gulp watch:test -c
2. Save a test file to kick off the re-building process
3. Before rebuild finishes, save again (might need to modify for watch to reload the file - in sublime text you can just save without modifying)
4. See the following error in the console (and chrome/phantom crashes, rendering the watch:test tasks useless):

Probably a karma bug, but I don't know.
