Entity hydration fails with QuoteStrategy enabled

[basz]

I've create a backtick quoting strategy.

Entity hydration seems to fail when I enable the strategy.

$user = $this->getRepository(User::class)->findOneBy(['email' => 'me@example.com']);

Errors with;

Undefined index: id

Seems to be the hydrateColumnInfo method in the sqlResult loop of SimpleObjectHydrator::hydrateRowData

When I replace

$this->hydrateColumnInfo($column);

for

$this->hydrateColumnInfo('`'.$column.'`');

Things work as expected.

Quoting strategy has been removed in Doctrine 3.x, now everything is quoted
