mode='remote' + dropdownAllowAll enabled and selected >> total changes we should keep currentPerPage to -1

[julius-spudvilas]

Expected Behavior
When dropdownAllowAll enabled + selected and total changes we should keep currentPerPage to -1

Actual Behavior
The currentPerPage is set to the total results value and that breaks the pagination dropdown as such option does not exists

Steps to Reproduce the Problem
Set dropdownAllowAll to true
Use mode='remote'
Get some resuts in table lets say 10
Then update results to anything else, let say 5
Pagination perPage dropdown breaks as:
after total changes the currentPerPage value is set to 5 and 5 is not available option in rowsPerPageOptions

line 146 should also check that currentPerPage is NOT -1
