Return the cached value if it's not time to scan again yet (#18)
* Return the cached value if it's not time to scan again yet

This should ensure that if we have a valid value cached (which ought
to be every time after the first scan), we return it as metrics.

This fixes the crashes that would happen if queries happened earlier
than the re-scan interval allowed.

* Address review feedback: Shorten the time-to-scan logic

We can express this in a single if statement, so it takes fewer lines
to do the "should we check again" check.
