Small/large file chooser

Created by: AnReZa

Right now, it looks like there aren't small or large file choosers. That's problematic, when you want to use the file chooser in a form, where all other fields are small. In the end, it looks rather ugly.

Or is there something, that I've missed or overlooked?

I already opened this ticket, but they say, that it's a bootstrap issue: https://github.com/bootstrap-vue/bootstrap-vue/issues/3285
