[3.1.191011] - Voting/Assets/Vesting - 404 error after "Switch Node"

**Describe the bug**
404 error after "Switch Node" or after connecting to another node.
Link `wallet.bitshares.org/#/account/test/voting` turns into a link `wallet.bitshares.org/#/account//voting`
`wallet.bitshares.org/#/account/test/assets` → `wallet.bitshares.org/#/account//assets`
`wallet.bitshares.org/#/account/test/vesting` → `wallet.bitshares.org/#/account//vesting` (related with #2878 )

**To Reproduce**
Steps to reproduce the behavior:
1. Go to [https://wallet.bitshares.org/#/account/test/voting](https://wallet.bitshares.org/#/account/test/voting)
2. Click on 'Switch Node'
3. Click on 'Connect to this API Node
4. See error "404 page not found", because the page has changed to `wallet.bitshares.org/#/account//voting`

**Expected behavior**
URL should not change

**Screenshots**

**Desktop (please complete the following information):**

**Additional context**
Pull request #2993 didn`t help solve the problem

Reproduce the failure by opening the voting, assets, or vesting URLs, then using Switch Node and connecting to another API node. Inspect the routing or navigation path involved and compare the behavior with pull request #2993. Done means switching nodes preserves the account segment and no longer produces a 404 URL.
