Description of problem:
Add input is automatically using Resource type also when value type is Plain, this is happening only when in previous input value type was set to search.

Version-Release number of selected component (if applicable):
sat 6.6 snap 16

How reproducible:
Always

Steps to Reproduce:
1. monitor -> report template -> create report template
2. inputs (tab) -> value type == Search
3. Add another input (button Add input) and there is automatically Value type Plain together with Resource Type - Activation Keys (which is wrong) 

For Value type == Plain there should be field Options and not Resource Type. 

Actual result: When user add another input, right after previous input where value type was equal to Search, then for Value type Plain there is still field Resource type.

Expected result: When user add another input, right after previous input where value type was equal to Search, then Value type Plain should display field with name Options instead of Resource type.
