Fix an issue with extractnumber_en_with_text

Articles (a, an, the) that appeared immediately before the number were
included in the returned text. This fixes those issues.

The solution isn't super clean - it craetes a new function to wrap the
old one (unavoidable, since the articles can be needed for fractions),
and splits the returned string, the strips leading artivles.

Since strings are immutable, this is probably not super efficient. Might
be better to eventually use lists as much as possible, and only create a
string at the end (though the lists will come with their own problems,
so that could turn out to be a wash). In any case, this works for now.
