Prevents exception for invalid dimension terms

While running outside of checked mode, parsing an invalid term expression
followed by a known dimension unit like

    width: Infinity%;

caused the following exception to be thrown:

    The getter 'text' was called on null.
    Receiver: null

Instead the parser now discards the invalid term, likely resulting in a useful
error message indicating the source of failure such as

    error on ...: expected }, but found %
      width: Infinity%;

Fixes #43.
