Filter current session after session removal

[omerxx]

copying the filter process from the main plugin function to reload sessions. This should fix #72 so that the current session isn't filtered if set so in the config.

Should fix #72

[sarojregmi200]

@omerxx Yes, it fixes the above issue ( #72 ) and has no additional bugs regarding the above issue. But as anticipated in the above mentioned issue it still is not a good fix. As it ignores other configuration such as:

set -g @sessionx-custom-paths '/custom/path'

And others are yet to be tested.

Got it @sarojregmi200 , I'm afraid there's no way around exporting this method.
I'll get to it soon and update

Yep, we are waiting for it do remember me if you need any help.
It felt good looking around bash script.
