main: Override global logError() function

logError() prints an exception with an optional prefix, and is
used fairly commonly through-out the code base.

The problem is that by being defined in gjs, it uses "Gjs" as the
GLib log domain, not our own as expected.

Address this by adding a small override that implements the function
with console.error().
