[fix](udf) avoid exception when fail to find udf in replay logic (#25965)
When replaying drop function edit log, the function may not be found, causing runtime exception and FE will fail to start. The function SHOULD be exist, but the reason is still unknown. I change the logic to NOT throw exception if function is not found. This is a workaround to make sure FE can start, and add some log for later debug.
