Missing comma in dependencies causes pants to emit "no valid targets found" instead of properly erring out.

[itayd]

for example, in a BUILD file:

python_library(
  name = 'foo',
  sources = ['foo.py'],
  dependencies = [
    pants('i forgot to put a comma at the end, here ->')
    pants('i am ok!'),
    pants('last one!')
  ]
)

then

./pants py foo

gives

"No valid target specified!"

I copied this issue to https://github.com/pantsbuild/pants/issues/86 so that Pants folks will see it. http://pantsbuild.github.io/howto_contribute.html
