The Reviews tab is missing in the Project Summary screen when having 2 FeCru instances integrated to JIRA

When having 2 FishEye instances integrated to a single JIRA, by certain FishEye Configuration, the Reviews tab will be missing from the Project Summary screen although the project has been mapped to a specific Crucible project:

Steps to reproduce the project:

• Add a single FishEye instance, map a JIRA project to Crucible project(s). The configuration for the following is set to "ON":
  • Disable for unmapped JIRA Projects
  • Force Project Mappings
• The Reviews tab will appear for the mapped project, as expected:
  
• Try to add another FishEye instance, with Crucible integration enabled
• The Reviews tab will be missing from the projects, and it's affecting the projects with mappings as well

Disabling the "Disable for unmapped JIRA Projects" option or removing the second FishEye instance seemed to fix the problem.

Also tested the behavior in JIRA 5.1.5 with FishEye 2.7.7, and it seems that the problem is not reproducible with the versions.
