MailjetTransport.php optimation

[kevinveenbirkenbach]

There are the following issues in the file MailjetTransport.php:

PHPDocs are wrong:

• some @parameters are not declared
• some @throws are not declared
• some @returns contain not all possible return types
• some @var use relative paths which can not be mapped by some IDE's e.g. (PHPStorm)

Logic:

• There is some logic which is unnecessary in the function bulkSend

Variables:

• $resultStatus is never used
• $sendCount is double declared
