FMXMemo writer: CachedLogWrite Begin/End messages appear together

[jachguate]

When the log is cached, a TjachLogToFMXMemo writer is registered and a call to WriteCachedLog is executed, the memo shows the Cached LOG Write BEGIN and END messages together, followed by all the cached messages.

The expected behavior is to show the BEGIN message, then all the cached messages and the END message afterwards.

A example log shows like this:

2022-03-29 00:22:49:554 00002DBC Info  Cached LOG Write BEGIN ********************
2022-03-29 00:22:49:554 00002DBC Info  Cached LOG Write END **********************
