cache-tree API: remove redundant update_main_cache_tree() 

Remove the redundant update_main_cache_tree() function, and make its
users use cache_tree_update() instead.

The behavior of populating the "the_index.cache_tree" if it wasn't
present already was needed when this function was introduced in [1],
but it hasn't been needed since [2]; The "cache_tree_update()" will
now lazy-allocate, so there's no need for the wrapper.

1. 996277c520 (Refactor cache_tree_update idiom from commit,
   2011-12-06)
2. fb0882648e (cache-tree: clean up cache_tree_update(), 2021-01-23)
