Mat-table with multiTemplateDataRows is not working when this table is added in mat-tab.

#### What is the expected behavior?
it should work fine with/without mat-tab

#### What is the current behavior?
Empty rows are created and displaying

#### What are the steps to reproduce?
Providing a StackBlitz reproduction is the *best* way to share your issue.

StackBlitz starter: https://goo.gl/wwnhMV

Step 1: Go to "https://stackblitz.com/edit/angular-material-expandable-table-rows?file=app%2Ftable%2Ftable.component.ts"

Step 2: Add Mat-tab module in app.module.ts "import {MatTabsModule} from '@angular/material/tabs';"

Step 3: Add the following code at the top, in table.componenet.html

"
Content 1
Content 2
Content 3
"

Step 4: Cut the rest of the code and paste it inside the tab replacing "Content 1"

Step 5: run the code.

Step 6: move to next tab and come back to first tab, the content will be displaying by default. PFA screenshots

#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?

#### Is there anything else we should know?

Start with the StackBlitz reproduction and compare table.component.html and table.component.ts before and after the table is placed inside mat-tab. Check app.module.ts for MatTabsModule, then reproduce the empty rows by switching tabs. Done means the multiTemplateDataRows table displays its content correctly after leaving and returning to the first tab.
