Fix panic in ProgramTestContext::warp_to_slot() when warping one slot (#22977)

Browse Source 
warp_to_slot() first warps to one slot before desired slot in order to
freeze the bank at warp slot. This would cause issues when warping by
one slot as that would attempt to warp to the same slot and hit a sanity
check assertion.
