using --force does not rewrite but appends model translations

[verybigelephants]

When using --force option, the generator re-writes previously generated model files with one exception and that is translation. instead of rewriting an existing array key 'admin.modelname' it appends a new 'admin.modelname' at the bottom of the file

i konw this is an easily solvable issue and you can simply erase the previously defined sub-array manually in a file, but it would definitely be nicer if the --force, that is semantically supposed to re-write everything from scratch, did it for me instead without having to manually navigate to files and rewriting them
