Fix: Make static assets take precedence over dynamic ones

[adzhindzhi]

Resolves

• Part of UEPR-402

Proposed Changes

• Update the logic in mergeDynamicAssets to make sure static assets take precedence over dynamic ones

Reason for Changes

• Some of the dynamic sprites use generic assets (e.g. the Pop sound). In order to prevent these sounds from appearing in the sounds library as member-only, we need to make sure the static ones take precedence during deduplication.
