prefetchtrees: allow only one revision to be specified as the base revision

Browse Source 
Summary:
The `prefetch` command only allows for one revision to be specified as
the base revision. Eventually, we plan to merge `prefetch` and `prefetchtrees`
into a single command and therefore, this commit takes a step towards making
the interface to these commands exactly the same.

Test Plan: Ran all the tests.
