George Kalpakas fb14945c02 fix(@schematics/angular): correctly handle adding multi-line strings to @NgModule metadata
Previously, `addSymbolToNgModuleMetadata()` assumed that the added
symbol would not span multiple lines. In most cases, the added symbol is
a single word, so this assumption was correct. In some cases, however,
we might want to add a mutli-line string, such as a static method of an
`@NgModule`:

```ts
  imports: [
    SomeModule.staticMethod({
      prop1: 'val1',
      prop2: 'val2'
    })
  ]
```

This commit allows `addSymbolToNgModuleMetadata()` to correctly handle
multi-line strings by ensuring that added metadata symbols are always
put on a new line (even if the array is empty) and each line in the
string is indented as necessary.
