Using profilefield_base_migration.php to create a custom profile
field with SQlite3 DBMS returns warning:
[phpBB Debug] PHP Warning: in file [ROOT]/phpbb/db/driver/sqlite3.php
on line 218: SQLite3Result::fetchArray(): Unable to execute statement:
constraint failed
This is due passing filed_id and lang_id to the DB driver in
unspecified format. As they are always int we should cast them
in int to prevent the error message appearance.

If extensions authors will use profilefield_base_migration.php
class as base class for creation of CPFs, the class need to be
extended a bit.
At the moment there are two issues with it:
It does not create entries for PROFILE_FIELDS_LANG_TABLE
(as it can't know what fields to create).
The migration is not "cleaning" the DBMS after purging
the extension and leaves everything except the CPF column.
Adding profilefield_language_data
PHPBB3-12786
The base migration class should create lang entry for the new CPF
but it is supposed to strip it of phpbb_ prefix. As extensions
CPFs do not use phpbb_ prefix it will not create a lang entry.
This is as simple solution as it can be done.
