The 'script' section finishes its execution prematurely whenever
a shell's exit is called. If the intention is to force
Travis to flag a build/test failure then the correct approach
is erroring any command statement. In this change, it combines
the grep's in a single AND statement that in case of false
Travis will interpret as a build error.
