Fix virtual repository tests - match package types for included repos

Fixed test failures caused by Artifactory's strict package type validation for
virtual repositories. Virtual repositories can only include repositories with
matching package types.

Changes:
1. BaseRepositoryTests: Modified to include localRepo (same package type) instead
   of genericRepo when creating virtual repos for package-specific tests
2. CustomPropertiesRepositoryTests: Removed enableComposerSupport from virtual
   repo test to avoid package type conflicts

This fixes errors like: "Virtual repository has package type 'Composer' but
includes non-matching repository with package type 'Generic'"
