Event Log is incorrectly reporting successful installations when it fails.

The PolyDeploy Event log is logging `PACKAGE_INSTALLED` events incorrectly for failed installations.

### Scenario 1:
1. Upload 6 packages for installation (Modules A, B, C, D, E & F)
2. 2 modules install successfully (Module A & B)
3. Event log records that modules C, D & E have correctly installed.

#### Scenario Notes:
- Modules B and F are theme modules with two packages in each (Skin and container).

### Scenario 2:
1. Upload 20 modules for installation (23 packages)
2. 19 modules install successfully (20 packages) and 1 module install fails (0 packages out of 3).
3. Event log records that 23 packages have installed correctly.
