Incorrect mapping of default expression for MySQL >= 5.6.4 CURRENT_TIME

[bizley]

What steps will reproduce the problem?

Create MySQL >= 5.6.4 table with timestamp(3) column and CURRENT_TIMESTAMP(3) as default value.
Fetch this schema in Yii 2.

What is the expected result?

$column->defaultValue = new Expression('CURRENT_TIMESTAMP(3)');

What do you get instead?

$column->defaultValue = 'CURRENT_TIMESTAMP(3)';

These lines are too strict now. I'll prepare PR with regex match and see if it's enough.

Quick and easy would be to use stripos and check if it matches 0.

if (($column->type === 'timestamp' || $column->type === 'datetime') &&
  stripos($info['default'], 'current_timestamp') === 0) {
  $column->defaultValue = new Expression('CURRENT_TIMESTAMP');
} elseif (isset($type) && $type === 'bit') {

Yes, if this is enough and matches all possibilities. I haven't dig into MySQL and MariaDB docs yet ;)
