Oracle adapter's quote_table_name returns quoted table name in uppercase and therefore it should be downcased before scanning downcased join_sql

Fixed adapter test cases that were failing in oracle because the asserts were looking for the presence of offset and limit which are not available in oracle. Changed the tests to check that the sql injection is not present in the output so that the tests are database adapter agnostic.

assert log output match in case insensitive mode to avoid failure when quoted table name is in uppercase (when using Oracle)

downcase table names in aliased_table_name_for and references_eager_loaded_tables? methods (as Oracle quoted table names are in uppercase)

latest oracle_enhanced adapter does automatic shortening of index names
ignore select from all_triggers table in assert_queries

(as otherwise was failing under JRuby and oracle_enhanced adapter)

Oracle enhanced adapter now supports shortening of default generated index names, some additional tests now pass

Reduced size of table name prefix and suffix in migrations test as in Oracle identifier name cannot be larger than 30 characters

(otherwise some tests are failing which assume that this attribute will have Date value)

(otherwise test is failing for oracle_enhanced JDBC adapter)

e.g. it guesses that a belongs_to association to Namespace::MyModel is
named "my_model", unlike before where it would look up an association
named "namespace::mymodel" and fail.
