If you just want the solution, then read Database Startup Fails With ORA-00119 (Doc ID 471767.1)
From standby database, startup mount resulted in the following errors:
ORA-00119: invalid specification for system parameter LOCAL_LISTENER ORA-00132: syntax error or unresolved network name 'LISTENER'
When setting local_listener, my preference is:
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=)(PORT=1521))' scope=spfile sid='*';
However, some implementations will use the following:
alter system set local_listener=LISTENER scope=spfile sid='*';
There are pros and cons to both.
When using LISTENER with tnsnames, modifications can be performed from tnsnames.ora without having to modify database parameters.
However, it’s not forgiving when there are misconfiguration.
Demo 1:
Modify local_listener and restart DB.

That’s not good!

Did you see the problem? Not sure why NAMES.DEFAULT_DOMAIN=world was set and remove solved the issue.

As demonstrated, having more options is not always good as it can lead to more likelihood for errors. Chose your evil wisely.
