[SPARK-32959][SQL][TEST] Fix an invalid test in DataSourceV2SQLSuite

### What changes were proposed in this pull request?

This PR addresses two issues related to the `Relation: view text` test in `DataSourceV2SQLSuite`.

1. The test has the following block:
```scala
withView("view1") { v1: String =>
  sql(...)
}
```
Since `withView`'s signature is `withView(v: String*)(f: => Unit): Unit`, the `f` that will be executed is ` v1: String => sql(..)`, which is just defining the anonymous function, and _not_ executing it.

2. Once the test is fixed to run, it actually fails. The reason is that the v2 session catalog implementation used in tests does not correctly handle `V1Table` for views in `loadTable`. And this results in views resolved to `ResolvedTable` instead of `ResolvedView`, causing the test failure: https://github.com/apache/spark/blob/f1dc479d39a6f05df7155008d8ec26dff42bb06c/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L1007-L1011

### Why are the changes needed?

Fixing a bug in test.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Existing test.

Closes #29811 from imback82/fix_minor_test.
