Fix ResourceID validation check expression

there are three methods which have wrong expression
getFallbackDrawable()
getErrorDrawable()
getPlaceholderDrawable()
According to the official documentation, resourceID can have a negative
value, so I modified the if statement logic to include correct validation.
