🦟 Bug fix

Fixes #378

Summary

The parser_urdf.cc file converts a URDF file to SDFormat. When converting a fixed joint, by default it merges the contents of the child link into the parent link. As noted in #378, the //sensor/pose is not properly adjusted during this merge process. This issue has already been fixed in newer branches by #525, so the test and that fix have been backported and refactored to reduce code duplication (about 30 lines removed from parser_urdf.cc) and also fix the treatment of //link/light/pose.
