New issue 3181: MetaData.reflect with "only" keyword fails due to wrong capitalization [Oracle]
https://bitbucket.org/zzzeek/sqlalchemy/issue/3181/metadatareflect-with-only-keyword-fails

Ivan Smirnov:

```sql
CREATE TABLE "FOO"."BAR" (
...
)
```

This works as expected:
```python
>>> engine.has_table('BAR', schema='FOO')
True
>>> engine.has_table('bar', schema='FOO')
True
```

However this doesn't:
```python
>>> meta.reflect(schema='FOO', only=['BAR'])
InvalidRequestError: Could not reflect: requested table(s) not available in oracle+cx_oracle://***:***@*** schema 'FOO': (BAR)
```
which only seems to works if names in `only` are manually lowercased:
```python
>>> meta.reflect(schema='FOO', only=['bar'])
```
