Frederic Massart 88474db22f MDL-50704 date: Fix invalid timezone mapping for +14 
The value Etc/GMT-14 was added to the list of known timezones,
and Etc/GMT+13 & Etc/GMT+14 were removed as they are not valid.

Tests were added to ensure that legacy user timezones are mapped
to known timezones. Other tests were changed to reflect the changes
with regards to Etc/GMT+13 and +-14.
