MOVE now can move TTL metadata as well.

Browse Source 
MOVE was not able to move the TTL: when a key was moved into a different
database number, it became persistent like if PERSIST was used.

In some incredible way (I guess almost nobody uses Redis MOVE) this bug
remained unnoticed inside Redis internals for many years.
Finally Andy Grunwald discovered it and opened an issue.

This commit fixes the bug and adds a regression test.

Close #2765.
