Speculative fix for build failures due to consumeInteger.
A recent patch added support for consumeInteger() and made
getAsInteger delegate to this function. A few buildbots are
failing as a result with an assertion failure. On a hunch,
I tested what happens if I call getAsInteger() on an empty
string, and sure enough it crashes the same way that the
buildbots are crashing.
I confirmed that getAsInteger() on an empty string did not
crash before my patch, so I suspect this to be the cause.
I also added a unit test for the empty string.
