Commands after teragrep exec syslog stream doesn't work if host and path parameters are given

[51-code]

Describe the bug

Using any command after teragrep exec syslog stream throws an exception from the parser if the host and path parameters are given.
Example query:

%dpl
index=abc | teragrep exec syslog stream host 12.12.123.123 port 123 | eval a=1

That will result to this exeption:

java.lang.IllegalStateException: Lexer failure on line 2, column 68 due to token recognition error at: '|'
Please check that the query is written correctly. Otherwise, please report this error and include the query used and this error.

This means that it doesn't recognize the pipe token after the syslog command.

If the host and port are removed, everything works.

Expected behavior

Should parse the commands after as well.

How to reproduce

Use the example query.

Additional context

[51-code]

There were no unit tests for the syslog stream command, so I created those. Also a specific unit test for this case with a command after it has been created now.
