Some Aggregation commands throw error message when 'count' is used as a field name

[Abigael-JT]

Describe the bug

%dpl
| makeresults count=5
| eval count = 123
| stats sum(count)

Returns:
java.lang.IllegalStateException: Parser failure on line 4, column 12 due to mismatched input 'count' expecting {METHOD_AGGREGATE_DQSTRING, METHOD_AGGREGATE_STRING_MATCH, EVAL_LANGUAGE_MODE_PARENTHESIS_L, EVAL_LANGUAGE_MODE_INTEGER, EVAL_LANGUAGE_MODE_DECIMAL, EVAL_LANGUAGE_MODE_EXCLAMATION, EVAL_LANGUAGE_MODE_NOT, ..... }

Expected behavior

Fields named after aggregation methods like count, avg etc, should not cause any issues when used with aggregation commands.
