[PepperBridgeAbstract] Fix Detection of "no deals found" and more (#3821)

- CSS styles showing there were no deals found has changed : CSS class
  was updated
- Relative Date handling : the minimum granularity of a relative date is
  the minute on the site. Seconds are therefore meaningless, and are now deleted.

MydealsBridge was missing one relateve date prefix : now every date is
parsed (I hope so !)
