Use more efficient entrySet iterator instead of keySet + get()

Browse Source 
The loop extracted keys from `remodeUidMap` and then called
`remouteUidMap.get(...)` for every key. If both the key and the value
needs to be iterated on, `Map.entrySet()` is a more efficient solution
as it doesn't require O(n) Map lookups.
