[BugFix] Intrinio Balance Sheet Period

[deeleeramone]

1. Why?:

   • A check that is used in the other statements to set the period shouldn't exist here because that is handled by a field validator. This made the line always validate to False because the value had already been mapped.

2. What? (1-3 sentences or a bullet point list):

   • Removed line.

3. Impact (1-2 sentences or a bullet point list):

   • More better now.

4. Testing Done:

   • Balance sheet, annual and quarter.
