Optimizes search-replace command by check if serialized data is present

Uses a regex search to see if serialized data is present in a column and
if not, runs a direct SQL replace rather than a serialized-safe replace
which is much faster. Also adds a safe flag to the search-replace command
which reverts the command to the previous behavior.
