Does not work for falsey values of name

Since the selected value is calculated using `(el.props.name || el.key)` falsey values of `el.props.name` cause the current tab to not be identified properly e.g.

```jsx

{ this.switchTab(el.props.name) }}
iconStyle={styles.tab}
selectedIconStyle={styles.selectedTab}
selectedStyle={styles.selectedTabText}

{this.props.children[this.state.currentTab]}
