Fix PR python/20129 - use of non-existing variable

PR python/20129 concerns the error message one gets from a command
like "disable frame-filter global NoSuchFilter".  Currently this
throws a second, unexpected, exception due to the use of a
non-existing variable named "name".

This patch adds regression tests and fixes a couple of spots to use
the correct variable name.

Built and regtested on x86-64 Fedora 23.
