patch 9.1.1498: completion: 'complete' funcs behave different to 'omnifunc'

Problem:  completion: Functions specified in the 'complete' option did
          not have the leader string removed when called with findstart = 0,
          unlike 'omnifunc' behavior
Solution: update behaviour and make behaviour consistent (Girish Palya)

closes: #17636
