Fix color contrast on 'View all templates' and 'Create templates' buttons

[stephaniesimms]

As an admin when I:

• click button to "Create a template"

• I see the New template page with a solid blue button in the upper right corner (screenshot 1)

• If I hover over the button, the text color changes to white "View all templates" (screenshot 2)

• If I click 'View all templates' and go back to the main Template page the 'Create a template' button is also solid blue (screenshot 3)

• the button remains solid blue when I reload the page

• Again, if I hover over the button, the text color changes to white (screenshot 4)

the text color is fixed now, but the button behavior is wonky:

• if I click to "Create a template" then click "View all templates" it won't take me back to the main Templates page

let me know if i should report this as a separate bug issue @briri

colors and button behavior are working as expected now. closing.
