Ensure to compile translation catalogs
Ensure to compile translation catalogs

A working directory in DevStack is not trove-dashboard directory,
so the directory path must be specified by an absolute path.

When I tested the devstack plugin for translation previously,
it seems compiled message catalogs existed and I didn't notice it.
