Bug 18898 - Some permissions for Reports can be bypassed

Bug 18898 - Some permissions for Reports can be bypassed

If you manually visit the following links when you only have
permission to run reports, you'll still be able to access the ability
to create and edit reports:

/cgi-bin/koha/reports/guided_reports.pl?phase=Create%20report%20from%20SQL
/cgi-bin/koha/reports/guided_reports.pl?phase=Edit%20SQL

This patch ties these 2 unaccounted for phases to the create_reports
permission.

With patch, issue no longer can be reproduced.
