Prepare for changes in how Truth prints class names.

Truth will soon:
- print only the simple name for some well-known classes (e.g., print "NullPointerException" instead of "java.lang.NullPointerException")
- print the canonical name where available instead of the binary name (e.g., print "com.google.Foo.BarException" instead of "com.google.Foo$BarException"

This CL updates callers to accept both versions.
