[#706] make substr index from correct character
[#705] remove_url_params supports multiple params

Sometimes is useful to remove more than one parameter from the URL to
clear a filter. This change does not modify any logic, just adds support
for the first parameter being a list instead of a string.

The value and replace parameters only will apply to the first element of
the list (or the provided param if key is a string)
