Fixes #195

Required moving all the tests which used internal/source to external test packages.

When scanning for an ast.CallExpr only consider those that use a ast.SelectorExpr where the name of the X is a gotest.tools package. That way if there are other function calls on the line, it will continue looking for the right call.

This makes the lookup logic more complicated, and will break if someone assigns assert.<func> to a local var. Hopefully that is not a common practice.

So package functions are called with the package selector. For the upcoming internal/source
change to handle multiple functions on a single line.
And change the test for multiple function calls per line, now that the lookup works
So that multiple function calls on the same line do not confuse the source lookup
