Allow symfony/deprecations-contract v3.0

[bravik]

Just to fix composer update issues, where composer prefers not to updated lexik bundle because it required deprecation-contracts v.2 and all other packages v3

dev@05584e3c9f0b:/app$ composer why-not lexik/jwt-authentication-bundle 2.14.1
lexik/jwt-authentication-bundle  v2.14.1     requires          symfony/deprecation-contracts (^2.4)
macroative/api                   dev-master  does not require  symfony/deprecation-contracts (but v3.0.0 is installed)
