IKEA_e2001_e2002 - Remove condition to check which button was released to trigger releas…

[jiridostal]

Proposed change

This PR removes a condition to check for the last value in the "input_text" to detect which button was pressed. This may not be an optimal solution and updating this PR with a new, working condition could be required. I did not figure out why the condition did not act as expected. Any contributions are welcome. This eventually closes #581

Thanks, this solved the issue for me where the release hook would not be triggered when releasing after long press. I'm using the STYRBAR remote via Zigbee2MQTT.
