Fixing TimeTest

This change contains three fixes:
1) The test for the French locale was incorrect (expectation of GMT+1
not GMT+2 for Paris).
2) The tests were sensitive to the locale setting of the device they
were run on. This has been fixed by modifying the way in which the
test sets the current locale. Additional problems were noticed but
these are fixed in a separate change for TimeFormatter.
3) Uncommenting some assertions that now pass.
