schedule: do not let us be disturbed by leading or trailing white space in names

my SPE9 deck contains quite a few wells which are somtimes named with
trailing spaces, sometimes without them...

there are other issues in this deck. probably the biggest is that the completions use glob matching for well names (i.e. "PROD*" for "PROD2"..."PROD26") which opm-parser interprets as repetition. I'm not sure how to fix that or even whether it should be fixed. Anyway, after this the full SPE9 deck loads provided that some unknown keywords in the summary section and the injector are removed. (I did not know how to fix up the injector, maybe somebody who has more clue than me can have a look.)
