The searchbar had a lot of lag when scrolling down the search
results view. This was due to a shared searchText variable which
updated every time the searchbar text changed and caused UI blocking.
Migrate searchText to a local variable and destroy the child
SearchResultsView as it's not needed at this time (may come back
with v0.7 due to searchable).
Also sources now display results progressively without a ProgressView
blocking when each source loads which allows the user to view media
faster.
