special case for reflective surfaces in pymoab tag naming

[shimwell]

Proposed changes

reflective surfaces were being prepended with "mat:" when using the pymoab export h5m method.

While most materials need prepending, reflective tags are a special case. So I've added special handling for that case

This tiny PR fixes the problem.
