Select all tables limit

[bradycharron]

I have a large multisite network with ~80 sites. This results in over 1600 tables. When I select all tables and run search/replace, it only grabs the first 998 tables. On the page reload that results from the successful running of the plugin, only those 998 tables are selected, and I have to select the remaining tables and re-run the plugin to get perform the search and replace on them.
