Fix RemoveGenericItemModal Controlled Component Warning

[llivne]

the following warning is shown when calling RemoveGenericItemModal (e.g. when deleting volumes):

Warning: A component is changing an uncontrolled input of type %s to be controlled. 
Input elements should not switch from uncontrolled to controlled (or vice versa). 
Decide between using a controlled or uncontrolled input element for the lifetime of 
the component.

I added the force to the state making the React state be the “single source of truth”.
