Numeric field views plugin is double-escaping special characters (apostrophe)

Problem/Motivation

Steps to reproduce:

1. Create a sample node type
2. Add a numeric decimal field
3. Create 2 sample nodes with field values greater than thousand (e.g. 10000 and 20000)
4. Create a view and select a numeric field
5. Enable aggregation on the view
6. Choose "SUM" aggregation type for the numeric field and select "Apostrophe" as a thousand marker
7. Save the view
8. Assert the output contains escaped ' values

Proposed resolution

Make sure the ' (apostrophe) special character is not escaped.

Remaining tasks
