This fixes a panic in the `SelectionsCollection::first_anchor` when there was a pending mouse selection and no other selections. Until recently, this method was only used in vim mode, but as of https://github.com/zed-industries/zed/commit/53b0720d546b6541fbf236d2f9d2dadbce6f126e, it's also used in the normal `move_up` and `move_down` actions. So until recently, the panic that this fixes could only happen in vim mode. Release Notes: - Fixed a crash that could happen when using certain cursor-motion bindings with a pending mouse selection.
