Snowflake LIST @foo and REMOVE @foo stage syntax fail to parse with a semicolon

[tv42]

-- breaks
LIST @bar;

-- ok
LIST @bar

-- breaks
REMOVE @bar;

-- ok
REMOVE @bar

This is starting to become a theme. See #1244, #1519.

1. can all the tests be made to test both with and without a semicolon
2. can the parser be generalized so whether a statement ends with EOF or ; isn't up to every individual statement

Weird workaround: add a space before ;
