Swap Delimiters functionality, swaps more than delimiters

[K3nZo87]

Describe the bug
When the swap delimiters functionality is used the dots inside function names, such as "PERCENTILE.EXC", get also converted to commas as if they were the decimal delimiter.

To Reproduce
Steps to reproduce the behavior:

1. Type a function name that contains a dot ("."), such as "PERCENTILE.EXC"
2. Use the swap delimiters functionality
3. The dot (".") gets converted to a comma (",")

Expected behavior
The expected behavior should be to swap all delimiters that are not a function name.
