#10719: restore messages generated on invalid compileall args

Before the introduction of filename arguments to compileall it gave semi useful
messages about not being able to 'list' names that weren't valid directories.
This fix restores that behavior.  In addition to the test for this case, the
patch also adds a test for the default behavior of compileall when no arguments
are provided, and fixes a bug in one of the previously added tests.
