Project pivot by group show nothing if group has a special character

[Sebastien Varupenne]

This project pivot report on "m&s" group shows nothing (see img1 attached) : http://jira.sylob.local/secure/ConfigureReport.jspa?projectid=&filterid=&targetGroup=m%26amp%3Bs&excludeTargetGroup=&projectRoleId=&startDate=02%2F06%2F14&endDate=06%2F06%2F14&showDetails=true&groupByField=&moreFields=customfield_10000&selectedProjectId=10700&reportKey=jira-timesheet-plugin%3Aprojectpivot&Suivant=Suivant

But, for example, gr is in "m&s" group and he adds some worklog for this period.

It seems that the problem appears only with "m&s" group and this is the only one with the special character "&".

Diagnosis: group is incorrectly encoded, e.g. targetGroup=m%26amp%3Bs+group Should be targetGroup=m%26s%20group
