Closes phpstan/phpstan#10367

Fix is the first commit 5e252bd

Second commit is just a refacto to reduce the number of method calls 26476e0

Since the method is almost always doing logic like

$type = $this->getOffsetOrProperty(...., false);
if ($type !== null) {
     return type;
} else {
     $type = $this->getOffsetOrProperty(...., true);
     // do things
}

It's better to directly return the type and the certainty and write

[$type, $certainty] = $this->getOffsetOrProperty(...., false);
if ($certainty->yes()) {
     return type;
} else {
     // do things
}
