The test "Budget Investments Show milestones" was failing in certain
cases where `Globalize.locale` had been changed in a previous test.
Since having different values in `Globalize.locale` and `I18n.locale`
has proven to be an issue on the test enviroment, this commit also
changes application code in order to avoid similar situations on
production.
See issue #2718.
The back button when the user changes the password
(in the print password page) redirects to the
edit manually page.
The routes to access password edit pages has been added,
along with the ones to send reset password email and
reset password manually.
This method is already existent in the application_controller but it
seems a little overkill to create a concern just for this method
Maybe when we have multiple method it makes sense to create a nice
controller. Another option would be to make the
management_base_controller extend from the application_controller
