Add cipher response to restore (#1072)

* Return revised ciphers on restore api call

* Return restored date from restore sproc

* Test Restore updates passed in ciphers

This is necessary for CipherController to appropriately return the
up-to-date ciphers without an extra db call to read them.

* Add missing SELECT
