UserHistoryDictionary currently uses locale to determine the
UserHistoryDictionary on the filesystem. With this change we
use the account name as well. Thus each UserHistoryDictionary
would following the following spec:

UserHistoryDictionary.<locale>.<account>.dict.
In case no account is selected, we default to the existing
spec:
UserHistoryDictionary.<locale>.dict

Example
UserHistoryDictionary.en_US.testaccount@example.com.dict

This will allow to greatly improve the performance of the
metadata-generating files, as they won't have to wait for
the info command to read the entire dictionary when the
header is all we need.

Also add tests, and while we're at it, use the seed as
intended to enable reproducible tests.

It's still unused as of this change but the next change will use it

As a reference point, generating the metadata for Bayo takes
3'02" on my machine with the info command; it's down to 16" if
made to use this instead. The gains increases with the number
of dictionaries obviously.
