Fix number formatting with different settings of precision in PHP

- fixed Util::formatNumber to avoid rounding issues to mess up display
- force precision = 14 to ensure we get sane behavior

With precision set to higher value many things do not behave as expected
producing strange numbers in various places.

For example with precision=19 you get:

php > echo round(1.2, 2);
1.199999999999999956

Fixes #12303
