[FIX] Mapping convertion using database

[R3VoLuT1OneR]

Hey I just found small "syntax" errors in "doctrine:convert:mapping" command.

Please merge the fix.

Please re-add the = to --from-database

[R3VoLuT1OneR]

@patrickbrouwers If remove it, code $this->option('from-database') === true never be true.

--from-database - Without = parsed as boolean ( set or not set ) and --form-database= parsed always as string. Because here we have option set/not set and no value required I think should be used --form-data.

@patrickbrouwers And in original doctrine command it is --from-database without =

Ah I was in the impression you could pass the database name to that option.
