JS crash on bad column in defaults

[nilesr]

Software and hardware versions

survey 210c

Problem description

If you supply defaults to addRowWithSurvey, like {"some_column": "default value"} and the column "some_column" doesn't exist, undefined is passed in to fromSerializationToElementType, which throws an exception and causes the page to never load. We should check its value around like 382 in database.js and display a warning instead.

Steps to reproduce the problem

add a row with bad columns using addRowWithSurvey

Expected behavior

displays a warning
