Check for self-references does not correctly deal with table expressions

Affected Checks
Check for unnecessary self-references

Expectation
If a local variable with the same name exists, the check should not emit findings for accessing an instance variable via me->

Actual Behavior
The check emits a finding for the following code (currently in /CC4A/SCOPE_OF_VARIABLE):

    if me->blocks[ result ]-type = if_ci_atc_source_code_provider=>block_type-sequence.
      result = me->blocks[ result ]-parent.
    endif.

even though a local variable called blocks exists.

Start by locating the implementation of the unnecessary self-references check, currently identified as /CC4A/SCOPE_OF_VARIABLE. Reproduce the reported ABAP snippet with a local variable named blocks and inspect why the table expression is treated as an instance-variable access. Done means the check no longer emits a finding for this case while preserving its other self-reference findings.
