Add Autocomplete Suggestions on My Events Search

[kb21032001]

Currently the search and autocomplete features function slightly incorrectly in the My Events page as the autocompleted suggestions search from the entire events database instead of only having suggestions for "My Events". The search result however, does still return the correct results i.e. only "My Events" are shown when the search button is clicked after typing in the search query. Minor issue but may require hefty work in the backend to solve.
