signing in after selecting checkout button, will not end up to checkout page!

[MMaKenZi]

If you open a magento store, add a product to cart, and try to checkout, and guest checkout be disabled, the login window will appear on screen,
but if you login to your account, you will be returned to homepage

while the correct page is checkout
because user clicked the checkout button before signing in

Preconditions

1. Magento 2.1.8
2. PHP 7.0.22

Steps to reproduce

1. disable guest checkout
2. open magento store
3. add product to your cart and select checkout button
4. fill the login window details
5. and you should select checkout button once again after signing in

Expected result

after signing in, user should redirected to checkout page, as he want this before signing in

Actual result

will be returned to homepage

@tkacheva Olena--can you consider this for backlog? I think it may make sense as a default as login at checkout is likely driven by desire to use stored address/payment info or possibly get a discount tied to customer account, but should do some research to confirm if it should configurable (to current or continue checkout).
