Wrong duplicate definition error for nested functions

[brubraz]

Describe the bug
Wrong duplicate definition error for nested functions.

To Reproduce
Steps to reproduce the behavior:

1. Create a function named "example()" in a nested match /databases/{database}/documents/collectionA
2. Create a function named "example()" in a nested match /databases/{database}/documents/collectionB
3. See error Duplicate definions with name example

Expected behavior
The plugin should not search for duplicated functions in sibling matches structures.

Screenshots

Possible solution
In src/main/kotlin/co/anbora/labs/firebase/ide/inspections/DuplicateFunctionsInspection.kt
DuplicateFunctionsInspection.kt

Concat the match path of the function in the key for comparison, at line: 29
val key = it.identifierExpr?.text + "_" + it.functionParameterList?.functionParameterList?.size
