Cleanup sentry errors for Create:Source Code

At the moment we have 931 Sentry errors assigned to source_code_management team.

https://sentry.gitlab.net/gitlab/gitlabcom/?query=is%3Aunresolved+feature_category%3Asource_code_management

Many of them are simple bugs caused by missing validation. We need to decrease their number to make Sentry usable for us.
