Finnish (fi) locale is forced in 5.5.3

Prerequisites

• [X] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [X] The issue still exists against the latest master branch of bootstrap-fileinput.
• [X] This is not an usage question. I confirm having read the plugin documentation and demos.
• [X] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [X] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. Use a few different language files, including fi.js.
2. Initialize fileinput component using javascript with any other language option.

A jsbin link: https://jsbin.com/xucomehoga/edit?html,js,output

Expected behavior and actual behavior

Finnish translation is always used instead of the chosen one. Probably because the Finnish translation is the only one with this line at the end:

$.extend($.fn.fileinput.defaults, $.fn.fileinputLocales.fi);

Environment

Browsers

• [X] Google Chrome
• [X] Mozilla Firefox

Isolating the problem

• [ ] This bug happens on the plugin demos page

• [X] I can reproduce this bug in a jsbin

The problem can't be reproduced when initializing fileinput with data attributes.
