Fixing the Shift functions Error by resolving a falsey bug with the Grapher Widget's asymptotes.

[SonicScrewdriver]

Summary:

There's been a long standing bug regarding Graphers in hints, which has been making quite a bit of noise in our reports. (This bug has been causing nearly 70% of our rendering errors!)

After investigating with @Myranae, we discovered that the issue was stemming from a bug in the truthy logic when determining whether to render an asymptote. Normally, the asymptote property is null for graph types that do not require it. However, I believe that our staticTransform method may have been changing the asymptote to an empty array, which was resolving as "truthy".

I've separated out this logic into a new property to properly handle this case. I've opted not to add new tests or to dig too much deeper into the staticTransform method as this was a time-boxed bugfix for a deprecated widget that is scheduled to be replaced with our Interactive Graph Widget in the near future.

Test plan:

• tests pass
• manual testing upstream to ensure Shift Functions page loads correctly
