Fix for bug #19736 VIEW: column names not quoted properly when view is replicated

When we write 'query=...' string to a frm file for views on a slave, 
indentifiers are not properly quoted due to missing OPTION_QUOTE_SHOW_CREATE 
flag in the thd->options.

Fix: properly set thd->options for the slave thread.
