Store View switcher not working on front-end and it throws an error

[latypatil]

If we select any store then site will go to that store and again we select another store then it throws an error because the url is wrong.

Preconditions

1. Magento ver. 2.2.0
2. PHP 7.0.24, mysql Ver 14.14

Steps to reproduce

1. Create different store view from admin panel and all will appear on front-end
2. Select any store view (No error)
3. Again select another store view(error will be there)

Expected result

1. It should show all store views without any error
   Ex. http://10.16.16.141/magento2.2/?___store=aus ==>this is for one of store view
   http://10.16.16.141/magento2.2/?___store=usa ==> This should be for different store view
   OR
   Base url should be the same for any store ,only store will get switch!

Actual result

1. [Screenshot, logs]
   

After changing the store view second time it redirect to below url :
http://10.16.16.141/magento2.2/?___store=aus?___store=usa

(URL is only for reference , it will not work)

The issue is in /vendor/magento/module-store/Block/Switcher.php with function getTargetStorePostData () where $store->getCurrentUrl(false) , Current url has been passed there and It should be $this->getUrl('stores/store/switch').
