title: Child router outlet works only one time
body: <p>The router outlet works only the first time. No issues or errors. I have a child routing to one component.
  Routing works correct URL is changing in a browser, but the component doesn't invoke the second time. </p>
  
  <pre><code>RouterModule.forChild([
      {
          path: '', component: InvestmentComponent, children: [
              { path: '', redirectTo: 'list', pathMatch: 'full'},
              { path: 'coin/:cointype/:hashaddress', component: MNWalletComponent },
          ]
      },
  ])
  </code></pre>
  
  <p>component html:</p>
  
  <pre><code> &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" routerLinkActive="active" routerLink="coin/{{coins[0].coin.coinType}}/{{coins[0].hashaddress}}"&gt; 
              &lt;appc-coin [coin]="coins[0].coin"&gt;&lt;/appc-coin&gt;
          &lt;/a&gt;
      &lt;/li&gt;
      &lt;li class="nav-item"&gt;
          &lt;a class="nav-link" routerLinkActive="active" routerLink="coin/{{coins[1].coin.coinType}}/{{coins[1].hashaddress}}"&gt; 
              &lt;appc-coin [coin]="coins[1].coin"&gt;&lt;/appc-coin&gt;
          &lt;/a&gt;
      &lt;/li&gt;
      &lt;router-outlet&gt;&lt;/router-outlet&gt;
  </code></pre>
  
  <p>What I do wrong?</p>
