Unable to save Blueprint Function Library if it references a string table entry

Regression.

Function library saving crashes if it references to a string table entry.

Project repro has been attached for convenience.

1. Open Unreal Engine Version 4.22 and create a new Blank Blueprint Project
2. Create a string table with a single string entry.(Key: TEST String: Test.)
3. Add & Save the String Table
4. Create a Blueprint Function Library "BFL_Test"
5. Create a "Test" Function which Outputs a Text.
6. Select the string entry from the created String Table.
7. Compile & Save.

Result: Editor Crash.

Expected: Successful Save.
