87d8ee755b changed the logging behavior
on Android to use the category as tag. But it was missed that
`formatLogMessage` only fills the fields given in the messagePattern.
Our default messagePattern includes the category but on Android it
is never filled since this change.
So we change the default messagePattern on Android to omit the category
and only use the category as tag when the category is not given in the
messagePattern.
