Subject: [PATCH] Don't update prev delta url (#4521)

<!-- PR description-->

URL cache should use the same delta token base used by `ProduceCollections`. This is because we want to update URLs for the set of items which was discovered by `ProduceCollections`. Otherwise, we'll have url cache misses & we'll have to resort to doing GetItem graph calls for each item which means we lose all goodness of the url cacche.

This reverts a change introduced in a recent [PR](https://github.com/alcionai/corso/commit/5215e907b05c25415e738c21a1292d33f74e3419#diff-f79ab9c9b31db3600d4e14b6df4d4c679b4356e32c3a68eaeaeb934c1c5a13a7R175) where we are updating cache's delta token base to a newer one.
