Fixed:

• skipped external downloads not registering as skipped/ignored correctly (This would cause the collection to fail to realize that installation had completed successfully)
• fixed bundled mod status potentially reverting back to "downloading" state (This would cause the installation to stall as Vortex was waiting for a bundled mod to download which would never happen)
• fixed incorrect/failed download lookups in collections extension causing the UI to fail to realize that the download is complete.
• fixed collectionsInstallWhileDownloading toggle not being adhered to.
• fixed downloads getting erased incorrectly during collection installation upon failure to rename them (added error handling for that use case which should guarantee it never happens again)
• fixed UI slowdown when installing recommended/optional mods (we were testing references for the entire collection not just the optional mods)
