When a proposal is created with a name that is longer than the max length of Varchar (255 characters?), we get an error 500 at create, rather than a clear user facing error about the title being too long. There should be 2 things done to fix this: * Add client side HTML limit of 250 characters for title name * Add validation in the project model checking that the name is < 250 characters See https://sentry.ewi.tudelft.nl/organizations/eip/issues/1201/
