[NTG-context] \switchtobodyfont behaves differenctly with splitted parameters

[Sylvain Hubert]

Hi Pablo,

thanks for the suggestion. Here's the minimal example which shows the
difference:

    \definefontfamily[face][rm][dejavuserif]
    \starttext\switchtobodyfont[face, 24pt]ɑ\stoptext

this should warn:

    fonts           > checking > char ɑ (U+00251) in font
'LatinModernMath-Regular-4' with id 10: missing

while

    \definefontfamily[face][rm][dejavuserif]
    \starttext\switchtobodyfont[face, 24pt]ɑ\stoptext

produces the expected result despite a harmless warning.
