test: Drop locale change check from TestPages.testBasic

The Python bridge does not dynamically change its locale from
`Accept-Languages:`, but just defaults to the standard environment of
the logged in machine.

We decided to not reimplement this in the pybridge, as that is weird,
error prone, and a corner case: No other Linux command line software
does that, it won't change the locale of existing running programs which
got spawned before changing the language (as that's impossible), the
code was making assumptions about locale names and availability, and we
take very little human readable text directly from command-line
programs, most of it gets interpreted, formatted, and translated in the
UI.
