Improve performance of Solis Modbus sensor

Removed unnecessary polling counter and scan interval in the Solis Modbus sensor. Also rearranged the order of operations in the time setting process to further optimize the code. The async write operation for the home automation state is now executed immediately after setting the time value. fixes #28
