Fixes bug #14902. When analysing a table with FT index that contains stopwords 

table statistics is not updated, so the next execution of analyze table will
try to update statistics again.

# Bug #14902 ANALYZE TABLE fails to recognize up-to-date tables

# minimal test case to get an error.

# The problem is happening when analysing table with FT index that

# contains stopwords only. The first execution of analyze table should

# mark index statistics as up to date so that next execution of this

# statement will end up with Table is up to date status.
