Uncaught Exception dispalys error screen in CFME UI

https://bugzilla.redhat.com/show_bug.cgi?id=1133747

When the user enters an invalid,incomplete path in simulation
during parsing we get the Ruby URI::InvalidURIError. Caught this error
and converted it to MiqAeException::InvalidPathFormat
The Simuation UI code only catches this exception and throws up the
error window for others.
Force binary in an expectation since UTF-8 is the default in ruby 2.0.

When reading ruby file contents, ruby 2+ encodes any Strings as UTF-8.
We have to force the encoding since WimParser returns either Fixnums or ASCII-8BIT Strings.

See: https://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/
