Page navigator with wrong URL when the result from a report has more than 100 records.

[anebi]

From management screen when click on some report t outpout the results (100 per page). If the results are more than 100, then on the top of the page appear page naviator (2,3,4,5 etc.). When we click on page 2 for example, the url is changing this way: h t t p : / / mydomain.com/trac/project/report/12?page=2

On page 1 the url looks this way: h t t p s : / / mydomain.com/trac/project/report/12?BILLABLE=0&UNBILLABLE=0&ASSIGNED=assigned&CLOSED=closed&NEW=new&REOPENED=reopened&STARTDATE=0&ENDDATE=2000000000

The page 2 and the rest (also <- and -> buttons) should have this url:

h t t p s : / / mydomain.com/trac/project/report/12?page=2&BILLABLE=0&UNBILLABLE=0&ASSIGNED=assigned&CLOSED=closed&NEW=new&REOPENED=reopened&STARTDATE=0&ENDDATE=2000000000
