TypeError in Assets::getFileKindByExtension()

[ostark]

Description

After saving an image (Asset editor / HUD) I get a TypeError.

[error][TypeError] TypeError: Argument 1 passed to craft\helpers\Assets::getFileKindByExtension() must be of the type string, null given, called in /Users/os/Projects/Craft/demo/vendor/craftcms/cms/src/elements/Asset.php on line 1215 and defined in /Users/os/Projects/Craft/demo/vendor/craftcms/cms/src/helpers/Assets.php

Lines 1214 to 1217 in 5b93c5e

	if (!$this->propagating) {
	if (AssetsHelper::getFileKindByExtension($this->tempFilePath) === static::KIND_IMAGE &&
	\in_array($this->getScenario(), [self::SCENARIO_REPLACE, self::SCENARIO_CREATE], true) &&
	null !== $this->tempFilePath) {

Changing the order of the conditions should fix it.

if (null !== $this->tempFilePath && AssetsHelper::getFileKindByExtension($this->tempFilePath) === static::KIND_IMAGE && 
                 \in_array($this->getScenario(), [self::SCENARIO_REPLACE, self::SCENARIO_CREATE], true) )
