New PandExo online version unable to load planet grid if "Resolve target" is used

[nespinoza]

Hi folks,

Leaving this here for completeness as I've already contacted @natashabatalha internally about this, and @mfixstsci is working on this: when doing "Resolve target" in the new PandExo online version (e.g., https://exoctk.stsci.edu/pandexo/calculation/new), one can try simulations with constant models and uploaded models, but when clicking "Select from Grid" on the "Planet model", the "Temperature" menu states "NO GRID DB FOUND".

Given this problem doesn't appear if one doesn't click on the "Resolve target" button, it is very likely this is a form validation issue.

Thanks in advance @mfixstsci for working on this!
