Signed flag not being respected

[luismavs]

In v 2.2.1:

alpha2digit('plus quatre avion', 'fr', signed=True)
'+4 avion'
alpha2digit('plus quatre avion', 'fr', signed=False)
'plus 4 avion'
alpha2digit('deux hélicoptères plus quatre avion', 'fr', signed=True)
'2 Hélicoptères +4 avion'
alpha2digit('deux Hélicoptères plus quatre avion', 'fr', signed=False)
'2 Hélicoptères +4 avion'

Happens for other languages too, probably associated with the existence of a previous number in the segment.
