Fix bug in `parse_formula` for formula's with leading or trailing whitespace

If a formula contains leading or trailing whitespace, one of the parts over
which the function loops will be empty, and so the regex match `m` will be
`None`. To prevent an `AttributeError` from being thrown when `group` is
called on `None` we check for it and continue.
