Change hard-coded ApplicationStatus while parsing

[hellsayenci]

The current Gmail parser works with hard-coded default ApplicationStatus. A flag should be added to ApplicationStatus table and the parser should insert the default ApplicationStatus while parsing.

• A "isDefault" boolean flag should be added to ApplicationStatus table with default value false.
• In the parser, the should check if the default status exists. If not create a new status with isDefault value is true. If exist, then add that default status to current JobApplication
