0020498: With big number of rows in ad_session SqlC somtimes fail with OOM regarding heap-space

Description

With a sufficiently high number of rows in ad_session sometimes compilation fails with an OOM error regarding heap-space when processing the SessionLogin_data.xsql file.

Checking it shows that the first method in that file does 'select * from ad_session' without any filters but is never ever called from the erp.

As the xsql-file is not public that dummy method should be fixed or just be removed.

Steps To Reproduce

i.e. compile on butler

Proposed Solution

Reorder SqlMethods in that file not require an unused dummy method.

Attached patch implements that (only compile tested)
