Fix T100731: Keymap Editor context menu crash

Caused by {rB3f3d82cfe9ce}

Since above commit, a `uiRNACollectionSearch` may contain a NULL
`search_prop`, crashing the menu entry for "Jump To Target"
(`ui_jump_to_target_button_poll`).

Now safeguard against this with a NULL check (getting search callbacks
to work for "Jump To Target" can be investigated in master).
