Subject: [PATCH] fix(maccatalyst): use the correct migrations path on the Mac
 Catalyst platform

Fixes #10 for Mac Catalyst platform, its likely the same fix will work for macOS in the future too.

Also fixes an issue when using `NSURL.absoluteString` on a path contains spaces, the spaces would
get replaced by `%20`.
