[SQL][MINOR] Fix warnings in DataSource/WriterV2Suites

### What changes were proposed in this pull request?
Fix compiler warnings in some DSV2 tests:   method schema in trait Table is deprecated (since 3.4.0)
Also some simplification (use analysisException() method in cases where its possible)

### Why are the changes needed?
Code hygiene to remove reference to deprecated method

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Existing unit test

### Was this patch authored or co-authored using generative AI tooling?
No

Closes #50523 from szehon-ho/fix_warnings.
