AWS SSM "search by..." bar disappears when typing search text

[ericvilla]

Describe the bug
AWS SSM "search by..." bar disappears when typing search text.

Leapp Version
v0.6.0

To Reproduce
Steps to reproduce the behavior:

1. Select "SSM Session" from a Session-specific three points menu
2. Select the specific region from which you want to gain the list of ssm-accessible ec2 instances
3. Type search text in the "search by..." that does not correspond to one of the ssm-accessible ec2 instances
4. Leapp hides "search by..." bar, so I'm not able to undo the research

Expected behavior
I expect Leapp not to hide the "search by..." bar, even if what I typed does not correspond to one of the ssm-accessible ec2 instances.
