Attribute [Tag] behaves different than [DisplayName] in case of overrides

[Ireanicus]

Hello,

I prepared minimal example of the issue here

When [Tag] attribute is placed on overriding method - it is ignored. However [DisplayName] follows overridden method attribute.
I think that Hangfire.Tags behavior should be aligned with the Hangfire behavior.

[Tag("base-class")]
public class BaseService
{
    [Tag("base-method")]
    [DisplayName("base-method")]
    public virtual void Run()
    {
    }
}

[Tag("overriding-class")]
public class OverridingService : BaseService 
{
    [Tag("overriding-method")]
    [DisplayName("overriding-method")]
    public override void Run() 
    {
        base.Run();
    }
}

Note1: I tested it also using PostgreSql Storage so it doesn't seem to be storage related.
Note2: There is other issue present in my example url (not related to this one)

I've done some digging for code causing this behavior:

Hangfire.Core HtmlHelper - DisplayNameAttribute handling (line 41 and 129)

Hangfire.Tags CreateJobFilter - TagAttribute handling. It seems like the Hangfire.Core itself is returning base method reference from filterContext.Job.Method

Fixed in 1.7.2. Basically: the filterContext contains the basetype of the method, and the type on which execution should take place. The dashboard get's the type on the derived type.
