Do not add silent mode history items to history

Browse source 
Prior to this fix, if you invoked fish with --private and then used
`read --silent` to read something sensitive, the variable would be
stored in history, with the plain text available through up-arrow.
Fix it to not store items in silent mode.

Note the item was never written to disk; it was only stored in memory.

Fixes #7230
