Leader election times seem too long with max current term

I use a fault injection tool to modify the term field of AppendEntriesRequest to max uint64.
When the current term is 18446744073709551615 (max uint64) , restart current leader node to start a new election.
It takes a long time to select a new leader(about 1min).
The testing system is rqlite.
Some crucial logs can be find in rqlite/rqlite#1712 (comment)
