Unable parse ESQL file with wrong comment sequence code

Hello,

I have found another problem when parsing ESQL file. The code is:

```
CREATE COMPUTE MODULE Test
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
/* OK comment */
*/
/* /* */ */
RETURN TRUE;
END;
END MODULE;

```

But in this case I know, that it is not correct ESQL code. I do not know, if ESQL plugin should analyze it too or not. I would understand, that such errors could be up to developer to correct is, the same like non-well-formed MSGFLOW.

And the reported error is:

```
ERROR: Unable to parse file: file:///C:/temp/temp/error05/Test.esql
ERROR: Parse error at line 5 column 3:

1: CREATE COMPUTE MODULE Test
2: CREATE FUNCTION Main() RETURNS BOOLEAN
3: BEGIN
4: /* OK comment */
5: */
^
6: /* /* */ */
7: RETURN TRUE;
8: END;
9: END MODULE;
10:

```
